; * lisp/vc/vc.el: Drop some old notes

Firstly, we are unlikely to do any unifying, because both amend
capabilities have been around for a long time now and we don't
want to break people's usage.  Secondly, there is now a plan for
dealing with dangerous git operations described in bug#64055.

New get-change-comment VC backend action

This gets us closer to using log-view-modify-change-comment with modern

Improve correctness of Eshell sub-forms

This makes sure that we treat Eshell sub-forms (whether Lisp or command
forms) as values when appropriate, or as regular invocations.  This

Simplify creation of Eshell command forms

Previously, Eshell over-aggressively converted subcommands, which forced
control flow commands to undo that change.

Fix c-ts-mode indentation for initializer lists (bug#73661)

The intentation behavior differed between c-mode/c++-mode
and *-ts-mode for initializer lists where the first element was
not at beginning-of-line.  The anchor-prev-sibling function gave
up and returned nil, but it should (probably) anchor on the
first element in the initializer list, such as this:

return { v1, v2, ...,
         y1, y2, ... };

c-ts-mode behaved better and figured out how to align, but I
added a test for a similar compound literal to prevent
regressions.
